* gpu: nvgpu: Add nvgpu_dma_alloc_vid_at()Terje Bergstrom2018-06-22

* gpu: nvgpu: Update Linux side VM code for API solidificationAlex Waterman2018-06-22
| | | | | | | | | | | | | | | | | | | | | | Update the Linux specific code to match the MM API docs in the previous patch. The user passed page size is plumbed through the Linux VM mapping calls but is ultimately ignored once the core VM code is called. This will be handled in the next patch. This also adds some code to make the CDE page size picking happen semi-intelligently. In many cases the CDE buffers can be mapped with large pages.

* gpu: nvgpu: Document VM map APIAlex Waterman2018-06-22
| | | | | | | | | | | | | | | | | | | | | | Provide concrete documentation for the VM mapping API. This shall be the gold standard! One of the major goals of this API is to keep the design simple. There are features that could be implemented in the kernel but were explictly chosen not to be. Example: partial mappings. The less work the kernel does the easier it is to verify against the API specifications. Security follows as well: the more simple the API the easier it is to ensure there are no easily exploitable corner cases.

* gpu: nvgpu: Update __get_pte_size() to check IOMMU-abilityAlex Waterman2018-06-22
| | | | | | | | | | | | | | | | | | | | When generating the PTE size for a given mapping the code must consider whether the GPU is being IOMMU'ed. The presence and usage of an IOMMU implies the buffers will appear contiguous to the GPU. Without an IOMMU we cannot assume that and therefor must use small pages regardless of the size of the buffer to be mapped.

* gpu: nvgpu: split gk20a_submit_append_gpfifoKonsta Holtta2018-06-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In gk20a_submit_channel_gpfifo the gpfifo entries can come from a kernel buffer or from userspace. To simplify the logic in gk20a_submit_append_gpfifo, extract out a function that copies the entries directly from userspace to the gpu memory for performance, and another function that copies from a kernel buffer to the gpu memory. The latter is used for kernel submits and when the gpfifo pipe exists which would mean that the gpfifo memory is in vidmem and is thus not directly accessible with a kernel virtual pointer. While this function is being changed a lot, also rename it to start with nvgpu_ instead of gk20a_. Additionally, simplify pushbuffer debug tracing by always using the kernel memory for the prints. Tracing when the gpfifo memory has been allocated in vidmem is no longer supported; sysmem is almost always used in practice anyway.
